Randy McDowell pleaded guilty to one count of possession of pseudoephedrine, knowing and having reasonable cause to believe it would be used to manufacture methamphetamine, in violation of 21 U.S.C. § 841(c)(2). The district court 1 sentenced him to 48 months’ imprisonment. On appeal, McDowell argues that the district court erred by failing to recognize or consider its authority to depart downward from the advisory guideline range. He also contends that the district court failed to consider the need to avoid unwarranted sentencing disparity, and imposed an unreasonable sentence. We affirm.
Prior to sentencing, McDowell filed a written sentencing memorandum and motion for a downward departure under the advisory sentencing guidelines based on his mental health, physical condition, and criminal history. Alternatively, McDowell *732 requested a downward variance from the advisory range for the same reasons. At McDowell’s sentencing hearing, the district court calculated an advisory guideline range of 63 to 78 months’ imprisonment, based on a total offense level of 25 and a criminal history category II. After hearing arguments from McDowell’s counsel, the court explained that it was “required to look at all the factors of 18 United States Code 3553(a) to decide a sentence to be imposed in this case.” The court discussed a number of issues relating to the § 3553(a) factors and sentenced McDowell below the advisory range to 48 months’ imprisonment.
McDowell first argues that the district court committed procedural error by failing to recognize and consider its authority to depart under the advisory guidelines. He claims that this error is evident because the district court proceeded to discuss the § 3553(a) factors without mentioning the requested departures. McDowell’s only objection at sentencing was “for procedural substantive reasons that the Court didn’t weigh the factors of his background and history appropriately.” This general objection did not give the district court notice and opportunity to correct the alleged error in the first instance, so we review for plain error.
See United States v. M.R.M.,
McDowell has not established that the district court failed to recognize or consider its authority to depart under the guidelines. “We presume that a district court is aware of the scope of its authority to depart,”
United States v. Patten,
McDowell next raises two arguments related to an alleged unwarranted sentencing disparity between his sentence and that of a codefendant, Lori Fisher. Fisher pleaded guilty to the same offense as McDowell, and the district court sentenced Fisher to 12 months and one day of imprisonment. McDowell claims that the district court committed procedural error by failing to consider the need to avoid unwarranted sentence disparities. He also argues that the “drastic difference” between the sentences establishes that the court abused its discretion when sentencing McDowell to 48 months.
The district court was aware of the need to avoid unwarranted sentence disparities *733 and expressly mentioned that statutory factor. In imposing McDowell’s sentence, the court explained that it had considered “the need to avoid sentencing disparity among similarly situated defendants facing similarly situated offenses.” Fisher, however, was sentenced more than one month after McDowell. McDowell’s argument, then, is that the district court erred procedurally by failing to consider disparity between McDowell’s sentence and a sentence that the district court would impose several weeks later, and that McDowell’s sentence was rendered substantively unreasonable by Fisher’s later sentence.
We review the district court’s consideration of the § 3553(a) factors based on “the entire sentencing record.”
United States v. Perkins,
Nor can the sentence imposed in Fisher’s case establish the substantive unreasonableness of the sentence imposed earlier in McDowell’s case. The parties in McDowell’s case had no opportunity to develop a record in the district court on potential differences between McDowell and Fisher that justified a longer sentence for McDowell.
Cf United States v. Maxwell,
The judgment of the district court is affirmed. McDowell’s motion to supplement the record on appeal is denied.
